Description

Hydroxylamine Phosphate is an important inorganic salt widely used as a versatile reducing agent and intermediate in industrial synthesis. Its unique chemical properties make it a critical component for processes requiring controlled reduction and the stabilization of sensitive compounds. This product is essential for manufacturers in the pharmaceutical, photographic, and specialty chemical industries seeking reliable and high-purity raw materials.

Application

• Pharmaceutical Synthesis: Key intermediate in the production of various active pharmaceutical ingredients (APIs), particularly oximes and hydroxamic acids.
• Photographic Industry: Serves as a stabilizer and reducing agent in photographic developers and other silver halide-based imaging processes.
• Chemical Synthesis: Used as a selective reducing agent in organic synthesis and for the preparation of other hydroxylamine derivatives.
• Polymer Industry: Acts as a polymerization regulator and chain transfer agent in specific resin and polymer production.
• Water Treatment: Employed in specific applications for oxygen scavenging and corrosion inhibition in boiler water systems.
• Analytical Chemistry: Utilized as a reagent in analytical methods for the determination of carbonyl compounds and metals.

Quality Control

Our Hydroxylamine Phosphate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for purity, identity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, impurity profile, and physical characteristics are provided to guarantee traceability and batch-to-batch consistency for our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) and easily oxidized nature, the container must be kept tightly sealed under an inert atmosphere after opening to prevent degradation and moisture absorption.
